<p>A waste disposal system (1) fits under a conventional kitchen counter and has a drawer (3) for receiving waste from the user and being over a grinder (4), in turn over a liquidizer (6) for liquidizing ground waste and delivering it to a drain. The drawer (3) accommodates a sliding hopper (11). The grinder (4) comprises a pair of contra- rotating rotors (20) having series' of teeth (21) in a spiral pattern to draw the waste downwards and grind it to provide particulate waste that is gravity fed to the liquidizer (6). The liquidizer (6) comprises an auger (32) for moving the particles into a cylindrical housing (33) which has a water inlet (34) towards the rear. The housing (33) also houses a chopper blade (38) which rotates about the same axis as the cylinder (33) just below the water inlet (34). The chopper blade (38) is fed with a flow of particles by the auger (32), and injection of the water at the inlet (34) both assists the chopping or blending action and provides the water for the liquidized waste stream. The system is quick and convenient to operate as there is no need for chopping up the waste before inserting it into the drawer (3). Also, it is particularly safe because the hopper (11) completely blocks access to the space above the grinder (4).</p> |
